STENCIL-CUTTING MACHINE.

Specification of Letters Patent.

Patented Feb. 22, 1910.

To alt whom it may concern:

Be it known that I, PAUL J. TvifoLi, a citizen of the United States,residing` at St. Louis, Missouri, have invented a certain new and usefulImprovement in Stencil-Cutting lvlachines, of which the following is afull, clear, and exact description, such as Will en able others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in Which- Figure l is a vertical section taken throughthe center of a stencil-cutting machine of my improved construction,with parts thereof shown in dotted lines. F ig. 2 is an enlarged detailsection of the upper end of the fixed post or standard on which therotating die carrier is arranged.

My invention relates to an improvement in the type of stencilcuttingmachines shown and described in Patent No. 808,308, issued December 26,1905, the principal 0bject of my invention being to rigidly fix a postor standard on the base of the machine, and upon Which post or standardthe die carrier of the machine is arranged for rotation.

A further object of my invention is to provide a simple connectionbetween the rotating die carrier and the pointer which op# eratesimmediately above the fixed indicating disk on the top of the machine.

To the above purposes, my invention consists in certain novel featuresof construction and arrangement of parts hereinafter more fullydescribed and claimed.

Referring by numerals to the accompanying drawings, l designates thebase of the machine and rigidly fixed thereto in any suitable manner isthe lovver end of the post or standard 2, the upper end of Which isreduced in diameter and screw-threaded as designated by 3. Arranged forrotation on the post 2 is the hub of the die carrier 4, and formedintegral With the upper end of said hub is a sleeve 5 which rotates in abearing 6 formed on the rear end of the arch 7 of the machine.

Located on the reduced screw-threaded upper end of the post 2, andbearing against the upper end of the sleeve 5, is a nut 8. Fixed on therear portion of the arch 7 is the usual indicator disk 9. Screw-seatedon the extreme upper end of the sleeve 5 and inclosing the nut 8, is acap l0, from the upper end of Which projects a pin ll, the same beingjournaled for rotation in a bearing formed in the center of the disk 9and fixed to said pin is one end of a pointer 12, the opposite end ofwhich terminates adjacent the letters and figures carried by the disk 9.Lock nut 13 is interposed between the cap l0 and the bearing 6 in orderto reduce the friction between said parts When the cap rotates with thedie carrier.

By rigidly fixing the post or standard 2 on the base, a very firmbearing is provided for the rotating die carrier, and such constructionis particularly advantageous when the machine is being assembled ortaken apart. The die carrier rotates freely upon the base or standard 2and as the cap 10 is carried by the upper end of the hub of said diecarrier, the pointer l2, carried by said cap, Will move With the diecarrier and indicate on the disk 9 the letter or figure corresponding tothe die beneath the operating handle of the machine.

Having thus described my invention, What I claim is:

1. In a stencil cutting machine, a base, a post located thereon, anindicator disk fixed on the frame of the machine, a die carrier arrangedfor rotation on the post, a member removably positioned on the hub ofthe die carrier a portion of which member is journaled for rotation inthe disk and a pointer carried by said member and adapted to traversethe face of the disk.

2. In a stencil cutting machine, a frame, a post fixed thereon, a diecarrier arranged for rotation on the post, the hub of Which die carrierextends through the frame at the upper end of the post, an indicatordisk fixed on the frame above the post, a member journaled in said diskand carried by the die carrier and a pointer carried by said member andadapted to traverse the face of the disk.

3. In a stencil-cutting machine, a base, a

post rigidly xed thereto, an indicator disk signature in the presence oftwo Witnesses,

arranged on the frame of the machine above this 2nd day of September,1909.

the post a die carrier arraned for rotation on the liost, a cap on theudper end of the UL J VOLF 5 hub of the die carrier7 and a pointercarried Vitnesses:
